Live Exchanger – How a plate heat exchanger works. In this video we will look at plate heat exchangers and how they work. Often called PHE’s, PHX’s, or sometimes just HX or HEX. The combination of the heat of the plate is very common. They are widely used in construction and manufacturing services. The reason they are popular is that they are very compact, they are very efficient, they are easy to service and require little maintenance.

The purpose of the plate heat exchanger is to transfer heat energy between two fluids, without mixing the fluids. For example, in the construction of services, you can transfer the heat from the primary loop connected to the boiler to a separate secondary loop, possibly in the district heating network. In production, you can cool oil with water, but obviously you don’t want to mix oil and water together.

An overview of the main components of a plate heat exchanger. We have end plates on the front and back cover, which are usually made of mild steel. They are very strong, they are there to hold everything together. Then we have the nuts, which connect and tighten the mounting bolts. The clamping bolts fit into the other studs on the side of the unit and will run the entire length of the heat exchanger. Bolts tighten on these bars and all the plates and gaskets together form a watertight seal. Between the end plates is a gasket and heat transfer plates.

Large heat exchangers will also have support bars at the top and bottom. This will help heat the mixture. Plates can only be removed for maintenance when the last plate has been removed.

Above is an example of a real earth heat exchanger plate. These are usually made of steel or titanium, and you may notice that they have a pattern or stamp on them. These systems increase the strength of the plates as well as the heat transfer surface area by creating a more intense flow in them. Heat flow is effective because it mixes the water so that the heat is evenly distributed or reduced. If the flow is correct, the temperature will increase in some areas more than others.

Between the plates we have gaskets, which are made of rubber. It is attached to the surface of the plate, and the purpose of the gasket is to ensure a good fit and prevent leakage. Gaskets also allow or prevent the flow of water through the sheet.

In the example of the actual heat exchanger plate, you can see a black line running around the outer edge, this is a gasket. Note that the two right holes have a rubber seal on them, this will prevent water from entering the plate. Although the hole on the left does not have this diagonal seal, fluid can flow in and out of the plate through this hole.

If you look at the picture of the previous example, compare the sizes of the heat exchanger. You can see that the reinforcing bonds are spreading away from the heat mixture. This is for several reasons. One reason is that all these plates have the ability to be suitable during installation or maintenance, but they also make it possible to expand the combination of heat plates in the future. For example, say a building is expected to expand in the future, so it can only expand its cooling capacity by adding more plates. It can also remove the plate to reduce it.

The most common is where all the inlets and outlets are on the front plate, so water will enter, flow through their channels, and then return to the front plate.

Another version is where the fluid enters through the front plate but exits through the back plate. Some water flows in the other direction.

The first version is the standard version and this is because you do not need to change the tube if you need to expand the plate heat exchanger in the future. For the second version, all the pipes that are attached must be removed and rebuilt to fit, depending on how far to extend your plate heat exchanger.

We connect multiple plates together and then use gaskets inside to prevent water from entering the replacement plate. The gasket can be rotated to close the hole on the right or left side. The two fluids will flow in each other way between the plates. Example: liquid 1, plate, liquid 2, plate, liquid 1, plate …

If we transfer the cold to the hot mixture, we can enter it through the upper left channel. It will then run on plates 2, 4 and 6. This will then produce high heat through the lower left side.

Then we have the hot fluid entering through the right channel, passing through channels 1, 3, 5 and 7. It will then exit through the upper right exit as low temperature.

What happens is the path between the plates is a different temperature and the hot always flows through the cold. So the hot liquid will transfer some of its heat energy to the cold liquid. The two fluids never meet or mix, they are always separated by a metal plate wall. Heat is only transferred that way. So the hot liquid will decrease and the cold liquid will burn.

You can also see that this water flows in a counter current. This is the best setting for maximum efficiency, because the log mean temperature difference, LMTD, is the largest.

If you encounter these in a building, make sure 1) they are insulated to conserve thermal energy as much as possible and 2) that protective sleeves are placed over hard load cables.
